This book is another adventure of Herge's brilliant imagination. Jo & Zette remind you of the innocence of TinTin, although their antiques are less sofisticated than TinTin, but nevertheless extremely captivating and cute characters. They try to help their father in winning Mr Pump's Legacy of $10M, and get into all sorts of strife thanks to their courage and wit. The monkey Jocko reminds you of Snowy (Milou)who brings another dimension to the story. Highly recommended for TinTin lovers of all age groups, and if you read this one you have to read Destination New York to find out what happens at the end.
